Glad to be of help, Willsy! Thanks for posting his Memorial photos, and thanks to Sandy for her photos, too.
Diana,
Do you know what Frank Jones' Regimental number was? It would be rather unusual for Frank to have arrived back from Egypt just before the war, as the 1st Battalion who went to France on the 12th/13th August 1914 were assembled from soldiers serving in England and a large number of Reservists who had served their "active" period of service and were back in civilian jobs but on Reserve duty.
The 2nd Battalion were out in Egypt at the outbreak of war, but did not reach England as a group until October 1914.
It's not impossible for him to have made it back to the UK if he shipped from Egypt just before the war, but I haven't seen an instance of it happening...
Steve.
P.S. From my database, I have two Frank Jones' with the 1st Northamptons.
8259 Cpl/Sgt Frank Jones - Enlisted in later part of 1906. To France 13-8-1914. Wounded as a Cpl. with 1st Battalion at Aubers Ridge on or around 9th May 1915. No discharge date on Medal Roll, therefore probably still in the Army in early 1920s.
7196 L/Cpl/Acting Sgt Frank Jones, enlisted in the latter part of 1903. To France, 13-8-1914. No details of wounding, etc. Transferred to Labour Corps, No. 704196 (very late number, possibly even post war).
P.P.S There are a couple of post-war "F Jones" pictures on the Northamptonshire Regiments Flickr site:
